Explanation:
1 When the target group is American adults, who very often have landline telephones and cellphones, it can be argued that including them will be more accurate.
4 This may be true; I can imagine that there are people, socioeconomically different, who don´t have (access to) landline phones.
6. Birthday doesn´t have anything to do with age, as suggested in nr. 5 and nr. 7. Birthyear does. The selection of most recent birthday in a household is a good way of selecting at random.
2, 3 and 8 are statements that don´t have any scientifical reasoning.
The colony of Pennsylvania was established by William Penn as a 'Holy Experiment'. It was given to him by the king in 1681, in payment of a debt he had to Penn's father. Amongst the other English colonies, Penn was the first leader of his colony that established peace with the natives. Then Penn made a peace treaty with the Leni lenape indians, and bought land from them. He hadn't needed to, but did anyways, and it was this act, as well as other kind acts towards the natives that formed peace between them. This also ensured a prosperous beginning for the new settlers of Pennsylvania, as the natives helped them with their crops, learning the way of the land and many such other useful things. Neither did they have wars that hurt the population
Answer:
producer; concentrated
Explanation:
Tariff and quotas are trade barriers that governments establish to protect national products. Tariffs are taxes imposed on imports and quotas are a limit on the quantity of a product that can be imported. These barriers are established when the government is willing to protect national producers when they are not able to compete with the low prices on the imported products. Also, the benefits of these restrictions are concentrated on the producers but its disadvantages affect all the consumers who have to buy products at a higher price. According to this, the answer is that tariffs and quotas are often imposed when a government is more responsive to producer interests, and the benefits of those trade restrictions are often concentrated.
